The Italian (R) and the Vatican flags' flutter on the plane chartered for Pope Benedict XVI's official visit to the United States, at Fiumicino International airport in Rome April 15, 2008. Pope Benedict left Rome on Tuesday on a six-day trip to the United States, during which he will pray at Ground Zero in New York.
The pope, who will also mark the third anniversary of his election during the trip, has said he hopes the visit will lead to a spiritual renewal in America.
He addresses the United Nations on Friday and has said he aims to draw attention to the need for greater peace and justice around the world.
In New York, Benedict will also make a brief stop at a synagogue to wish the city's Jewish community a happy Passover.
He ends the trip on Sunday after visiting Ground Zero, the site of the World Trade Center towers destroyed in the September 11, 2001 attacks on the United States. He will also say Mass at Yankee Stadium. (Reuters)
